TERMiNAL-BLOCK yATTACHMENT.

This invention relates to a terminal block attachment for storagebatteries, and has for its object to provide, in a manner ashereinaft-er set forth, an attachment of the class referred to foreliminating corrosion at the battery terminals, enabling batteriesof thesame dimensions to be interchangeable, and to overcome the providing ofbatteries with different styles of terminals.

tive post of the'battery will gradually crack,

allowing the acid to creep up the post and eat on the brass, orcomposition of brass,

connection. The locking screw then becomes corroded in the threadandwhen attempt is made to remove the screw, it requires a greater pullatthe terminal in order to do so, regardless of what character of toolis employed. To overcomev the objections stat-V ed is the primary objectof this invention and which is attained by connecting the terminals ofthe terminal block tothe terminals of the batteryvby' lead wires whichare burned V`onto not only the block terminals but also the batteryterminals making a sure tight connectionat either. end of a Wire andthen applying a sealing composition at the .n

Vconnections between the bloclr terminals and the wires so that suchconnections will be acid proof and air tight from the bottomA thereof,and as battery acid has no bad eifect on lead there is no chance ofcorrosion of the terminals of the terminal block. K

Further objects of the invention are to irovide in a. manner ashereinafter set forth,`

of iarts, as hereinafter more specifically described and illustrated intlieaccompanying of theinventiomfbut it is to beunderstood that changes,variationsand modifications cante resorted to "which come Vwithin thescope of the claims hereunto appendedi Iny the drawings wherein likereference characters kdenote corresponding throughout the several viewsFigure l is atop plan view of a storage battery showingy the adaptationtherewith of a terminal block vattachment in accordance with thisinvention.

- Referringto the drawings in detail, l denotestlie bodyportion of astorage battery, 9. the positive terminal of" the battery, 3 ther*negative terminal of the battery, 4 the positive terminal of the,terminal block, 5 the negative terminal of the terminal blocln' acoupling elementy for the terminal block, and 7 a housing of insuiationforming an element of the terminal block.

Extending from the terminal 2 to the terminal 4s is a lead conductor 8,and extending from the terminal 3 tothe terminal 5 isa lead conductor 9.b

The housing Twhich preferably, is substantially semi-oval in crossrsection, is

opened at each end and at its bottoinand closed at its top. rllhehousing 7 has the outer face of its top formed with a rcctangih 'lar'portion A10 of alength less than' the length of the housing and thelatter forms a substantially@semi-oval shaped chamberk l1 vwhich isclosed at its top and open at each end and at its bottom.- Extendinginto the .chamber 11 atone end thereof is a conductor 8 and at its'otherend a lconductor 9. The top of the housing 7, at a point between its. ytransverse center and'each end is provided ywith an opening whichextends through the vrectangular portion 10,'and the Jsaid openf` ingsare indicated at 12, 13 and are arranged at the longitudinal center ofthe housing.v

That end ofthe conductor 8 which extends intojthe chamber 1l isupturned` in,atli`rec- "ion towards the openiii'giZ, as indicated ai'.ii, and .that and if the epnductor which extends into kthe haniber 1l isuptuined, as

at to extend in a direction towards the opening 13. rilhe upturned end14 of the conductor S is spaced from the upturned end 15 ot theconductor 9 and the said conductors 8 and 9 are positioned above thebottom of the chamber 11.

The terminal 4, as Well as the terminal 5, consists ot a bolt or screwof substantial length and diameter and Which is peripherally threadedthroughout and indicated at 1G. The terminal 4, as Well as vthe terminal5, includes a nut 17 carried by the bolt or screw 16 and which isarranged in abutting relation `with respect to the rectangular portion10 at the top of the housing 7, and each of said terminals is'furthermore provided above the nut 17 With av Wing nut 1S forsecuringbattery Wire connections. The terminal 4 extends down through theopening 12 and the terminal 5 down through the opening 13. The terminal4 is extended into the upturned portion 14 of the conductor S and theterminal 5 is extended in the upturned portion 15 ot the conductor 9.The upturned portion 14 is burned on the terminal 4 and the uptnrnedportion 15 is b urned on the terminal 5. The upturned portions 14 and l5snugly engage the side Walls and top of the chamber 11, as shown inFigure 3.

After the conductors S and 9 have been burned onto the terminals 4 and5, the chamber 11 is then tilled with a battery sealing compound 19 andsaid compound is flush with the bottom and each end ot' the housing 7and such compound makes the chamber 11 acid and air tight from itsbottom and protects terminals 4 and 5 so that they will not corrode.

rllhe conductor S is burned onto the terminal Q and the conductor 9burned onto the terminal 3, and said conductors 8 and 9 are ofsufficient size to carry any load that the battery can pnt out. Theburning Vot the conductors 8, 9, on the terminals 2 and 3, as Well asthe burning ot' the conductors 8 and 9 on the terminals 4 and ,5,provides a sure tight connection at each end of said conductors.

The coupling element 6 is in the form of a steel strap and consists of avertically extending arm 2O and a horizontally disposed arm 21 whichprojects inwardly at right angles with respect t0 the upper end of thearm 20. The arm 2O is secured to the body portion of the battery by thehold-fast devices Q2, and the arm 21 is mounted on the housing 7 betweenthe terminals 4 and 5 and further is secured to said housing 7 by ahold-ast device 23. The couplingelement being iixedly secured to thebody portion 1 of the battery takes all the strain and vibration of thecircuit connections which are attached to the terminals .4 and 5 andwhich would be delivered to the terminals 2 and J 3 if such connectionswere attached directly to said terminals, and by this arrangement thelife of the battery is increased as it is Well known that vibration andshaking is very detrimental to the internal parts ot storage batteriesresulting in the shortening of the life thereof.

It is thought that the many advantages of a storage battery terminalblock in accordance with this invention can be readily understood,particularly in view oi the tact that the `corroding of the terminals isovercome and that it can be readily installed on any and all kinds ofstorage batteries, and although the preferred embodiment ot theinvention is as illustrated and described, yet changes in the details ofconstruction can be had which Will fall within the light ot' theinvention as claimed.

that I claim is:-

1. A terminal block comprising a housing of insulation having a groovein its bottom side and spaced holes through its top side communicatingwith said groove, conductors extending into opposite ends ot saidgroove, said conductors having their ends bent to extend into saidholes, terminals tor said conductors extending through the holes andembedded in the conductors, said terminals carrying means exteriorly of'said housing for securing' to said terminals circuit connections for thebattery, and a sealing compound Within said housing and enclosing ltheportions of said conductors therein. A

2. ln combination, a housing` of insulation open throughout its bottomand further open at each end, a pair of spaced oppositely disposedconductors each extending into said housing at one end thereof andformed with an angularly disposed upstanding inner end, terminalsextending through the top .of the housing and each having its lower endembedded in one ot thel angularly disposed ends ol a conductor, and asealing compound enclosing the inner terminal portions ot` theconductors Within the housing.

3. In combination a housing of insulation formed with an open bottom andfarther open at each end, the top of said housing being iat and providedwith a plurality of holes, a conductor extending into said housing ateach end thereof, a pair of terminals supported by the housing andextending through the holes in the top thereof and connected to theinner terminal portions of said conductors, a sealing compound Withinsaid housing, and means secured to the flat top of the housing forsuspending the latter. In testimony whereof, I atiix my signad turehereto.
